Application filed February 8, 1899. Serial No- 704,901- (No model.)

To aZZ whom it may concern..-

Be it known that I, ANTON KREIDLER, manufacturer, residing at Stuttgart,in the Kin gdom of Wiirtemberg, Germany, have invented new and usefulImprovements in Wire-Covering Machines, (for which I have applied forLetters Patent in Germany, K. 17,0336 of September 10,1898, and inEngland, No. 208, of January 4, 1899,) of which the following is aspecification.

This invention relates to machines for covering wire with yarn and thelike by winding, in which a gang or multiple sets of winding or coveringmechanisms are employed. At-

tempts have been made to render these sets I independent of each otherby arranging them in such manner as to be able to stop themindependently, and this has generally been effeoted by automaticallystopping each set on the breaking of a thread; but this has necessitatedcomplicated mechanism, and, moreover, it was difficult to provide theparticular set in question with a new thread or to piece up the brokenthread with a new thread while the adjacent sets were still in workwithout stopping the machine altogether.

This invention has for its object to obviate this disadvantage by soarranging the mechanism as to render such sets independent andenabletheiroperation to beseparatelystopped and a broken thread to beeasily pieced up while the adjacent sets are still running and withoutstopping the driving mechanism, the operation of removing a setbeingefiected by swinging it forward, as on a pivot, so as to temporarilydisconnect it from the driving mechanism. To enable this to be done, itis necessary to make each set complete in itself with all itsappurtenances, which has'the further advantage that the sets are therebymade interchangeable-that is to say, each is capable of being removedand at once replaced by another already prepared outside the machine inreadiness for work-and this may be done before piecing up the breakageor repairing the defect which necessitates the exchange. Such facilityfor exchange and independence of the sets enables any change of work tobe made on part only of a machine in response to a sudden demandnecessitating the throwing out of gear of some of the sets in workwithout interfering with the remainder of the work on the machine, orthe whole of the sets may be so exchanged, if necessary, and the newwork proceeded with until the job is finished. Moreover, the progress ofthe work of the various sets of covering mechanism may be so timed thatthey may be exchanged in rotation, so that a single attendant only willsuffice to superintend the whole machine, whereas in the machines asheretofore used this could not be conveniently done, since it was onlywhen the whole machine was at a standstill that the necessary quiet andsafety for the service of the individual sets could be insured. Themachine is therefore much easier to supervise and occupies much lessspace than other machines of the same capacity now used.

According to this invention the several sets of covering mechanism areseparately mounted in narrow auxiliary frames arranged side by side inthe same plane, the frames being pivotally and removably supported bytheir lower ends resting in half-round bearings in cross-bars atopposite sides of the main frame, against which the auxiliary framesrest in a rearwardly-inclined position. The covering mechanisms of allthe sets are actuated bya driving mechanism common toall, consisting ofa friction-drum extending the whole length of the main frame,with whichthe sets of mechanism are in frictional driving contact at both sides ofthe main frame, so that by tilting any one forward through a small angleit will be thrown out of gear or may be removed and exchanged. Eachauxiliary frame contains the usual covering mechanism,the naked wirebeingdrawn from a spool through tubular spool-carrying spindles, over adraft-roller, through a winder-guide, onto the windingroller.

In the accompanying drawings, Figure 1 represents a front view of asingle set; Fig. 2, an end view of the machine, and Fig. 3 a front viewof same.

The main frame of the machine consists of the end standards B, braced bythe bottom bars 0 and the top bar G, on which are carried racks E forsupporting the auxiliary frames A laterally. The driving-cylinder J runsthrough the whole length of the machine and constitutes what I term themain drivin g means. Each set or auxiliary frame A.

ism.

rests by its bottom cross-bar A in semicircular bearings in the bottombar 0 (see Fig. 2 and leans at a slight backward inclination, its upperend being engaged by a rack E, attached to the top plate.

In Fi 3 the auxiliary frames A are shown as placed close together in themain frame; but although all are similarly fitted only the auxiliaryframe on the extreme left is represented as fitted with all itsappurtenances, which comprise the usual winding mechan- The naked wireruns from the spool a through the spindles b and I), over thedraftroller 0, through the traversing guide y, to the winding-roller d.The spindles b and b are driven through the endless cord f, running overguide-pulleys g and g from the frictionwheel 6, which is driven byfrictional contact with the driving-cylinder J. The draft-roller c isdriven by the cord Z and drivingear k m and the train of cog-wheels n pq, motion being imparted from the shaft of wheel 6. The winding-rollercl is driven in the usual manner by means of drivingear v at and acooperating cord 10, and the guide 3/ for the Wire receives traversingmotion through the cord driving-gear s u and a cooperating cord or belt15.

On the right side of Fig. 2 one of the frames A is shown as disconnectedfrom the drivingcylinder J.

It will be evident that the sets are entirely independent of each other,so that both the kind of material to be employed as well as the speed atwhich the wire is drawn off and the number of windings or turns of eachset can be altered at will. This machine is specially suitable for lightwork and for all kinds of covering material, such as textiles, and alsofor india-rubber, paper, and the like.

Now what I claim, and desire to secure by Letters Patent, is thefollowing:

1. In a wire-covering machine, the combination of a main frame, amovable auxiliary frame, winding and covering mechanism carried therebyand means for carrying the ma terial operated upon and the take-offmechanism therefor upon the auxiliary frame.

2. In a Wire-covering machine, the combination of a main frame, aplurality of separate independently-movable auxiliary frames,independent Winding and covering mechanism carried by each of saidauxiliary frames and means for carrying the material operated upon andthe take-off mechanism therefor upon each of the auxiliary frames.

3. In a wire-covering machine, the combination of a main frame, aplurality of separate auxiliary frames movable with relation to the mainframe, independent winding and covering mechanism carried by each ofsaid auxiliary frames, means for carrying the material operated upon andthe take-off mechanism therefor upon each of said auxiliary frames and asingle main universal driving means carried by the main frame, which isadapted to cooperate with the individual driving mechanism carried uponeach of the auxiliary frames to operate the movable parts thereof,whereby when any auxiliary frame is in one position its respectivedriving mechanism will be operated and when said auxiliary frame is inanother position, its driving mechanism will be disconnected and thrownout of operation.

4. In a wire-covering machine, the combination of a main frame, aplurality of separate auxiliary interchangeable frames independentlymovable and removable from the main frame, independent winding andcovering mechanism carried by each of said auxiliary frames, means forcarrying the material operated upon and the take oif mechanism thereforupon each of said auxiliary frames and main driving means carried by themain frame, said main driving means cooperating with the winding andcovering mechanism carried upon each of the auxiliary frames to operatethe movable parts thereof, whereby any auxiliary frame may be removedand replaced without affecting the operation of the other parts of themachine.

I11 testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

ANTON KREIDLER.
